摘要: A submersible pump-motor assembly (10) for use in dispensing petroleum from petroleum storage tanks (12). The pump-motor assembly (10) of the present invention enhances the performance characteristics of the pump-motor assembly (10) by providing greater flow area around the motor stator (59) while maintaining the alignment of the assembly's critical pump components. A shell (56) having an expanded portion (58) encloses the pump assembly (54) and the motor unit (52). The expanded portion (58) of the shell is disposed around the motor stator (59).
